ACETYLENE-LAMP.

Specification of Letters Patent.

Patented Mar. 2o, 1917.

Application led August 10, 1915. Serial No. 44,767.

To all 'whom .it may concern:

Be it known that I, JOSEPH MESSINA, a citizen of the United States, residing at Benld, inthe county of Macoupin and State of Illinois have invented new and useful Improvements in Acetylene-Lamps of whichi the following is a specification.

A the carbid container is regulated at will,

thereby varying the production of gas during the use of the lamp.

A further object of the invention 1s they provision of a lamp of this character wherein the water feed tube is constructed so as to avoid the accumulation of dirt therein and to prevent the clogging or choking of the same, which would interfere with the feed of the water from lthe reservoir to the carbid container of the lamp.

A still further object of the invention is the provision of a lamp of this Character which is simple in construction,- thoroughly reliable and etlicient in its operation, strong,

durable and inexpensive of manufacture.

With these and other objects in view, the

invention consists in the construction, combination and arrangement of parts as will be, hereinafter described, illustrated inthe accompanying drawings, and pointed out in the claim hereunto apended.

In the drawing:

Figure 1 is a side elevation of a lamp constructed in accordance with the present invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a vertical longitudinal sectional view of the same;

Fig. 4 is a sectional view on the line 4-4 of Fig. 3;.

Fig. 5 is an enlarged fragmentary verti. cal sectional view through the water tube valve and water feed tube;

Fig. 6 is a side view of the annular-hood or housing removed from the lamp; and

Fig. 7 is a bottom plan view thereof.

Similar characters of reference indicate v corresponding parts in all the views of the drawing.- Y

' Referring to the drawing in detail, the lamp comprises a body A including an uplper water reservoir 10, and a lower carbid container or holder 11, the same being formed with a contracted externally threaded neck 12 detachably engaged in the lower sleeve-like portion 13 of the water reservoir 10 for connecting the same. Formed in the reservoir 10 below the `bottom 14 thereof is a gas circulating chamber l5, while depending from and integral with the said bottom 14, centrally thereof, is a water feed tube 16 which protrudes into the container or holder 11 for supplying Water from the reservoir to the same. Removably fitted within the neck 13 of the container v or holder 11 is a disk 17 which has integrally formed therewith at its upper side a circularv or annular hood or housing 18 which is concentrically disposed about the water tube 16 and is formed with an eX- -ternally threaded central apertured sleeve for detachable engagement with theexternal threaded enlarged portion 19 of the water tube 16, while depending from the lower side of the said disk 17 is a tubiform guard or cage 2O which is disposed concentrically about the water tubel and is split at its lower end to form semi-circular Wings 21 to enter the body of carbid within the container or holder 11 for the production of gas.

Formed in the disk 17 and establishing communication between. the container or holder 11 and the housing or hood 18 is anwick 23 it its coiled formation. This wick 23 serves as a conductor for the gas from the container or holder 11 and has its opposite end protruded through an opening 25 formed in the peripheral wall of the said engages the end of the water feed tube 16 on the turning of the stem 29 in one direction, while on turning it' in the opposite direction the valve end 20 will be disengaged from the end of the water tube 16 and in this manner the feed of water from the reservoir 10 to the container orfholder 11 is regulated. -On the outer end of the stem 29 is a finger arm or lever 31 so that the stem 29 can be readily turned by the hand of the user of the lamp.

Formed on the top of the reservoir 10 is a filling nipple 32 closed by means of a hinged cap 33, and through this nipple is adapted to be introduced water into the reservoir. Located about the neck 12 of the container or holder 1l is a rubber gasket 34 which forms'a tight joint between the sleeve-like portion 13 of the reservoir and the said container or holder. Likewise, concentrically disposed about the hood or housing 18 and working against the circular flange 35 formed interiorly of the sleeve-l1ke portion 13 of the'reservoir 10 is a rubber gasket 36 which forms a tight joint between the disk and the said flange so as to avoid leakage of the gas through the joint between the container or holder 11 and the gas chamber 15 in the reservoir 10 of the lamp. It will be apparent that the opening 22 which receives the wick 23 is completely occupied by the wick so that the gas from the holder 1l will have to permeate the wick before it is delivered to the burner tip.

From the foregoing it is thought that the construction and manner of operation of the device will be understood and, therefore,

a more extended explanation has been omitted.

Having thus described my invention,-I claim:

A carbidilamp including a water recepprising an independent element centrally formed with a sleeve-like extension to encircle the tube and adapted to be removably connected with said tube, and an annular hollow head carried by the sleeve extension,

yand iitting within the gas chamber, said annular head having a transverse partition, and being formed wlth an opening on one side of said partition to estabhsh communi- 'cation between the head and carbid container, and an opening on the opposite side of the partition to establish communication between the head and gas chamber, and a wick arranged in the head with its terminals on opposite sides of the partition, and immediately adjacent the respective openings.

In testimony whereof 1 aiilx my signature in presence of two witnesses.

JOSEPH MESSNA.
